+long-tap events</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>Long-tap events allow you to specify functions performed when the user
+taps and holds the button for a specified period of time. An example of a
+long-tap function is fast forwarding in a media player application by tapping
+and holding down a button.</p>
+<p>To receive long-tap events, use the class <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknLongTapDetector.html" format="application/java-archive"><codeph>CAknLongTapDetector</codeph></xref> in the <xref href="GUID-92018B6B-3CBB-434D-9E61-F271C67E98E3.dita">Touch
+UI utilities API</xref>.</p>
+<p>To enable the handling of long tap events in your <codeph>CAknButton</codeph> ,
+set the flag <codeph>KAknButtonReportOnLongPress</codeph> for the button.
+When the long tap event starts,<codeph>CAknButton::ELongPressEvent()</codeph> is
+reported to the button observer (<codeph>MCoeControlObserver</codeph>). When
+the long tap event ends, <codeph>CAknButton::ELongPressEndedEvent()</codeph> is
+reported.</p>
+<p>To define the period for which the button needs to be held down for a long-tap
+event, use the method <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknButton.html#5b5323936073f454e96847337131030a" format="application/java-archive"><codeph>SetLongPressInterval()</codeph></xref> in the class <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknButton.html" format="application/java-archive"><codeph>CAknButton</codeph></xref>.</p>
